Biotrue Multipurpose Solution from Bausch & Lomb is a contact lens cleaning solution that works like your eyes to ultimately help make wearing contact lenses easier. Biotrue Multipurpose Solution has a dual disinfection system for superior disinfection; it provides up to 20 hours of moisture in each drop; and it matches the eye’s natural condition, which enables optimal activation of the disinfectants. This is not your average contact lens solution. Not only does it have a lubricant found naturally in eyes, it also matches the pH of healthy tears and helps keeps some tear proteins active. These proteins are natural germ fighters, which helps further Biotrue’s antimicrobial properties. All of these factors combine to make your contact lenses more comfortable over a longer period of time.
